Single atom imaging by annular dark field (ADF) STEM Chicago STEM ~1975 Nion UltraSTEM 2007 Nion UltraSTEM 2010 � 40 keV: 2.5 Å Au atom 100 keV: 1 Å Au atom 200 keV: 0.6 Å Au atom � The resolution has improved, and so has the stability. � In ADF STEM, the potential well around the nucleus is imaged. ADF STEM can thus potentially show atoms as only about 0.3 Å large. � From Ondrej Krivanek
EELS from nucleic acid bases From: M. Isaacson, 1972
Energy Loss Spectra of Metal Fluorides M. Scheinfein and M. Isaacson, J.Vac.Sci.Tech.B4(1) 1986. 326 – 332.
